Multi-Agent Observability: Why One Trace Isn't Enough

This post introduces the concept of multi-agent observability, detailing the challenges of tracing and correlating actions across multiple agents, shared memory, and external tools. It identifies the 'attribution gap' and 'context fragmentation' as key problems and proposes a shared state layer, potentially leveraging Redis, to improve observability by correlating decision metadata, inter-agent messages, memory operations, retrieval quality, tool interactions, and identity/permission scope.
